This stylish automatic watch from Seiko has a black dial with a date function all housed in an elegant stainless steel case.

This watch takes its design cues from the original ‘Alpinist,’ first launched in 1959 exclusively in the Japanese market for Japanese ‘Yama-otoko’ mountain men, to be reliable in treacherous terrain. The 2021 version is designed for practicality – powered by the Automatic 6R movement with highly visible lumibrite on the dial and hands – easy to see in any light.

Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike.
